Specification of Letters Patent.

Patented March 9, 1909.

Application filed July 29, 1907. Serial No. 386,066.

To all whom it may concern:

Be it known that I, Avnms J. GABRIELIAN, a. citizen of the United States, and resident of Boston, in the county of Suliolk and State of Massachusetts, have invented an Il.\1- provement in Lastii 'Ma.chines, of which the fol] owing description, in connection with the eccompenyin drawings, is a. specification, like numera s on the drawings representing like parts.

My invention relates to the lasting of a shoe constructed substantially as shown in my Letters Patent No. 821,935 of May 29, 1906, in which the welt and upper are sewed to ether before bein lasted.

tnted briefly, I "US'l, insert the last, pulling over in usual manner the welt and upper on the last sufiiciently to get them in op- The upper is then tacks 1n usual manner to the lost, the heel end of the upper heingtncked down in usual manner to the heel end of the shank piece or a heel piece. My apparatus and method may also 2e used for lasting my shoe up or and attached welt to a usual mnersolc, and in the latter case the heelart of the upper is tacked to the heel end 0 the innerso e at this stage. Then, having placed the last and shoe upper in in machine, I adjust the letter so as to bring the toe of the upper close to the toe-lasting or t0e-1nolding or lightly downward at the some time upon the bottom of r the last so as to lift the welt into a. list osition by means of the supporting edges 0 the molding late. The toe tack or tacks are then pu ed, rovided they have not been previously pu led, and the upper and welt together with the contained lost, are pressed forward against the edge of the molding plate so as to bring them into a proximately accurate position and cause em to conform to the shape of the molding plate.

Thcrcu on prefembl a knife or blunt tool is run in hetween the net and the edge of the welt and upper so as to remove any wrinkles that me. possibly be present. The forward edge of t e welt at the too is then clam ed 111 place and the last and upper ere pulls hepk so to stretch. aii tne iooscness of the leather toward the toe. Then downward pressure is brought u on the last to distend this looseness upwor ly and move the botare used, are similarly moved tom of the last into a plane just under the molding plate, whereupon the molding plate and lost are moved toward each other. As

the molding plate rests against the seam which joins the edges of the upper and welt, this forward movement of the est stretches out all the loose leather and molds the up or to the desired finished shape. Also, the side Wings of the molding plate, provided they in for accomplishing the same purpose slo the sides of the shoe. The ressure wh ihll has been holding is lost own during the stretching movement is now relieved, as the molding plate and side portions thereof hold the arts in their shaped position and the w t is beaten down to n erfectly smooth surface, if not already so ciently smooth, and the welt is tecke down. on the last, or innersole, as the case may be, the toe portion thereof is released from its clamped osition, the molding mechanism is backs oil, and the last and lasted shoe are put on the rack to dry. Thus, it will be seen that by my machine I accomplish at the some time the lasting, molding or shaping of the shoe and sides, and provide it smooth welt surface. This reduces the number of machines necessary, makes it ossible to simplify the mechanism considers ly, and produces a shoe having the advantages set orth in my before mentioned patent. Instead of securing the welt after the shoe is lasted, the welt 13 secured before the shoe is lasted, and forms an important aid in the lasting operation. No esting pincers are necessary, and the usual wipers are not employed, so that the danger of tearing the leather with pincer-s or injuring it withthe herd sliding pressure of the wipers is obvieted.

Further details of my invention will eppeer in the course of the following description, taken with reference to the accompanying drawings, in which I have shown one of many contemplated embodiments of the apparatus.

In the drawings Figure 1 represents 111 side elevation the head, or operating portion of the machine, parts bein.% brok cn away for ciesrness of illustration ig. 2 is a, top plan view thereof, showing the parts ready to receive a shoe; F' 3 is a cross sectional view showing a. shoe ieing lasted; and Fig. 4 is o sectional detail showing the shoe being clamped.

On a suitable base plate 1 adaitcd to be secured to any convenient pedesta orstandard, is an upright 2 and bracket 3, in which reciprocatos a jack-carrier or lastsupport 4 carrying a jack 5 at its rear end adjust-ably secured by a hand not 0, and provided at its upper end with. a heel rest 7 and heel spindle or pin 8, having threaded adjustment in a block 9 loosely p1voted at 10 in a support 11, adjustable in a slotted arm 12 secured adjustubly in place by a hand not or wheel 13. The carrier or slide 4 is operated by a screw 14, having threaded en ngeniont with the upright 2, and operated by a hand wheel 15 so as to move the jack 5 forward and backward as the most convenient means for securing the relative movement. of the shoe and last with relation to the remaining portions of the lasting mechanism. At the upper end of the upright 2 is a cross head or top 16 which rejects forward and laterally at its back sire at 17 and at 18 at its front side to receive opppsite guide plates 19, and to so port at its ack side a rosser bar or arm 0, whose slotted end 21 s ides freely on a pin 22 of a post 23, pivotally mounted in the art 17. At its front side 18 the cross head supports not only the plate 19 but a treadle rod 24, hav'mg a hook 25 at its upper end, and a trcadle 26 at its lower end, said rod being movable laterally in a slot 27. The presser bar has a presser foot or block 28 to engage the shoe bottom, and is capable of being movably engaged by the hook 25 adjacent its outer end at 29, according to the requirements and convenience of the oper ator. Beneath the slides 19 I mount a molder or shaping plate 30, whose side portions or win 31 are herein shown as loosely pivoted at 3 to the main part of the molder or shaping plate, and normally held with an outward tendency by any convenient means, as by a spring 33. These side wings are operated by any convenient means, either separately or together, small hand levers 34 being herein shown for swinging up into ongagement with the outer edges of the wings to crowd the same forward into lastin r position to operate the same as alreai y de scribed in connection with the main operation of the shaping plate or molder 30. The molclcr is made as a thin plate and is removable, so that it can be used for a left shoe with the side up shown in the drawin s, and for a ri ht shoe when reversed with ti o o posite si e up, it being understood that this shape of the plate controls the she e of the shoe, and must correspond substan why to that elf the last. It is malady for permit t this use of the same mechanism for both rig ts and lofts that I have given thelastr supporting portion of the ack ractlcally univeisal movement, sothat the eel end 01' the last ma be freely moved or swung toward one si( e or the other as desired. The receiving slot of block 9 in su iport 1] is wide enougl to permit lateral sliding of the block 0, wliicn can also tip in the same direction because of the loose pivoting at 10, sec dotted lines Fig. 1, and can ti J in the opposite dircrs tion on said pivot. 'llie cross head 16 also projects rearwardly at 35 to support an overhanging bracket 36 having dovetailed engagement therewith at 37, and adjustable by means of a hand screw 38, said carrying a clamping arm 39 pivoted at 40 and normally held by a spring 41 a ainst an adjustable stop 42, and given quidlt downward movement by the cam end 13 of a hand lever 44 pivoted at 45. The forward clamping foot or end 46 of the clamping device 1s pivoted and removably held 1n place by a pin or screw 47, so that it may be swung slightly horizontally to the right or left to fit a right too or lert too, as the case may be, and to permit a different shape to be substituted according to the various styles of toes lasted, and also to permit a sli ht lateral swing. The toe of the shoe is yie ldingly supported by a toe rest 48, loosely sup- )orted on a 9 ring 49 in a bracket 50, adustably held y a clamping nut 51 against the adjacent part 2.

In use, the shoe upper, having been pulled over a last by hand as already on )lained, is placed in the machine, as shown in *ig. I, the heel spindle or pin 8 occupying the heel of the last, and the toe resting on the toe rest 48. The hand wheel 15 is then rotate-d over to the left, thereby pulling the shoe and molding mechanism together until the. toe lasting or shaping plate 30 engages the shoe up er all about the toe beneath the welt, whici rests down upon the top of the forming edge of said plate 30. His operator meanwhile swings the resser 20 over the fore )art, bringing slig it downward pressure to car, so as to get the bottom edge of the last aproximatoly even with the shaping edges of he molder 30, preferably catching the book 25 over the handle of the pressor so as to operate the latter by the foot, removes the lasting tacks, if an from about the toe, and runs a knifeor b unt tool under the welt and upper around the edge of the last, so as to remove all wrinkles or tendency of the leather to form plaits. He then turns the hand wheel 1.5 over further to the left, until the edges of the molder 30 press the 11 )per hard against the last. He then quic tly shifts over to the 1" 1111 the handle 44 of the cam lever 43, whicli instantly clam. s the toe portion of the welt between the c cmping b ock 46 and the molder 30. Thereupon the and wheel is turned in reverse direction so as to back the 'ack 5 away a short distance to the right, an the operator pulls rearwardly on the last so as to stretch all loose leather forracket 1 ments coo eratin to bring the shaping edge molding plate.

of the m0 ding p ate 30 just above the bottom of the lastand to move the last forward beneath said plate, the latter operating, through its engagement against the welt seam, to crowd the welt inwardl bottom of the last sufficiently to ast the upper. This combined inward and upward stretching movement on the leather (it being understood that the downward pressure of the presser results in an upward ull on the leather by the shaping plate) resu ts in shaping perfectly the toe portion of the IIJPCI. The edges of the side wings are place( beneath the welt at the sides of the shoe, and the handles 34 are then turned up, with the result that the side wings are quickly and iirmly pressed forward strongly against the welt seam, thereby quicklyand effectually shaping and molding this ortion of the fore- The we t is then tacked in the usual manner to the'last, the handles 34 are turned back, releasing the side wings of the moldcr, the prcsser is unhookcd and swung out of the way, the jack is backed away by turning the hand wheel 15 over to the right, and the shoe is disengaged from the moved and put on the rack to dry or set in usual manner.

If my method is used for lasting a shoe upper in connection with a usual innersole, it will be understood that an iron bottomed last is employed, so that when the tacks above mentioned are driven through the welt they are caused to clench on the under side of the innersole, thereby holding the welt and innersole together in the lasted shoe.

If the o erator has been lasting right-foot shoes, am it is desired to change to lasting lofts; the plate 30 is simply slid out from its holding recess, turned the other side up, and reinserted. Then, when a shoe and its u per are put in position, the heel portion 0 the shoe is swung around to the necessary extent to cause its toe portion to occupy the proper relation to the molding plate, and the operation proceeds as before. It will be observed that the heel rest 7 of the jack is curved for this purpose, and it will be understood that it is cus ioned or added to prevent injury to the heel of the s 100. If a different shape of toe is to be lasted, the plate 30 is removed, and a similar late having its inner curve conform ng to t e new style is inserted. If a change 18 a radical one, the clamping block 46 is also changed, and a different clamping block having a new shape is inserted. The practically horizontal movement of the presser enables the operator to direct the pressing movement thereof in practically any direction, according to the requirements of over the The lasted shoe is then re the work. The 'heel post is given the delicate adjustment shown in order that the angle of the forepart may be accurately determined thereby, as I have found this to be the'most handy means of accomplishing this purpose.
